TWENTIETH ANNUAL REPORT OF THE DIRECTOR. 13 



means or through entire rc-arrangement of the grounds (for 

 which, at some future time, plans are prepared in detail), 

 necessarily prevents any considerable annual increase in the 

 number of plants used for this purpose; but this restriction 

 of their number has been met, year by year, by increase in 

 their variety and attractiveness, by the adoption of purposeful 

 combinations of species, contrasted groups of related forms by 

 which attention may be centered on them in their general 

 characters, and by the combination of this synoptical idea in a 

 broader way with the plans for decorative effect, whenever 

 this can be done. In the year just closed, therefore, the out- 

 of-door decorative features have been little different from 

 those reported a year since, except for changes in bedding 

 design and substitutions in the plants employed in carrying it 

 out. As for several years past, tulips formed the attractive 

 feature of early spring, when the parterre was planted solidly 

 with them, the collection of these bulbs comprising 229 species 

 or varieties, represented by 23,750 individual plants. Later 

 in the season, the same space was used for the presentation of a 

 contrasted collection of the choicest lantana varieties, which, 

 though for the most part too heavily beset with foliage for a 

 proper balancing of their flowers, proved attractive as well as 

 interesting and instructive. Through the interest of an 

 amateur in the cultivation of cannas, Mr. L. D. Yager, of 

 Alton, Illinois, the display of these showy plants has this year 

 been doubled, and no feature of the Garden has been more 

 admired, or more critically approved by specialists, than this 

 collection of 160 varieties, represented by 560 massed plants. 

 Chrysanthemums were again grown in large numbers, and 

 through the fortnight beginning with November 9th, a tented 

 display was made of 452 varieties, represented by 3,582 plants, 

 many of them of unusually good size and quality. 



The addition of twenty acres to the Garden in 1900* not 

 only added nearly one-half to the original area of the grounds 

 (44.7 acres), but made possible the realization of one of the 

 early-declared policies of the Board, to present a segregated 

 representation of the plants of the United States; of these
